Deciduous Teeth

LLU Tooth Morphology of premolars; high yield * & Blue Book questions

M-D crown width greater than I-C crown height (only anterior tooth with this characteristic)* Deciduous maxillary central incisor
"Incisal view: M-D width noticeably wider than F-L dimension (MD>IC>FL) " Deciduous maxillary central incisor
"M-D width greater than F-L (IC>MD>FL) (circular outline) " Deciduous maxillary lateral incisor
"M-D, F-L and I-C crown dimensions nearly same* Outline diamond shape " Deciduous Maxillary Canine

"Crown is unique - does not resemble any other molar* (more similar to premolar’s) " Deciduous Maxillary 1st Molar
"Facial CE line has depth of curvature towards mesial* (vs. others are Lingual more Apical) " Deciduous Maxillary 1st Molar
"Root divergence is greatest of all primary molars* " Deciduous Maxillary 2nd Molar
"Closely resembles permanent maxillary first molar* " Deciduous Maxillary 2nd Molar

"Distal of occlusal table wider than mesial* " Deciduous Mandibular 1st Molar
"Deciduous Mandibular 1st or 2nd Molar? All three facial cusps more similar in size* " Deciduous Mandibular 2nd Molar….note, the 1st has 2 facial (not 3...), and 2 buccal cusps.
Deciduous Eruption Sequence "1. Central incisors 2. Lateral incisors 3. 1st molars 4. Canines 5. 2nd molars *Rule: mandibular precedes maxillary "
"Presence of a cervical ridge on facials of all teeth as well as linguals of all anteriors* " Deciduous Teeth
The only primary or secondary incisor where the mesiodistal crown dimension is greater than the incisocervical crown dimension. Primary Maxillary Central Incisor
These deciduos crowns are symmetrical "just like" each other when viewed facially, lingually, or incisally "2nd Mandibular Central Incisor & Primary Mandibular Central Incisor"
The primary _____ is bilaterally symmetrical when view facially or lingually. Primary Mandibular Central Incisor
The incisal edge of the _________ is horizontally straight, the only primary incosor to display this trait. Primary Mandibular Central Incisor
The cingula of this primary tooth extends much farther incisally than the cingula of its secondarys. Maxillary Incisors; 2nd Incisors
The apical aspect of tooth roots curves facially. Primary Anterior Teeth
Has a mesial proximal contct that is located cervical to the distal proximal contact, the only primary tooth with this characteristic. The uniqe primary dntition feature is shared with the secondary ______ . Primary Maxillary Canine; shared with Manidbular 1st Premolar
Has the longest root of any primary tooth. Primary Maxillary Canine
Facial surfaces of incisor crowns are usally smooth and there are no depressions. Primary Anterior Teeth
The CE line on the linguals is more apically located than on the facial. Primary Anterior Teeth
Has a crown form that does not resemble any other primary or secondary (permanent) toothe and because it is so different "it appears strange and primitive". Primary Mandibular 1st Molar
Has the second most variable crown form relative to other primary and secondary teeth; although one author indicates it bears a resemblance to secondary premolars Primary Maxillary 1st Molar
The mesiolingual cusp is the "most conical" of the primary and secondary molar cusps. Primary Mandibular 1st Molar
The distolingual cusp is "a bulging protuberance" on the distal aspect of the tooth that is a unique cusp form. Primary Mandibular 1st Molar
____ have a narrow occlusal table. The ____ has an occlusal table which is the narrowest found on any primary or secondary molar. Primary Molars; Primary Mandibular 1st Molar
From a facial view, the outline form of the mesial surface of the crown is "uniquely straight" in an occlusocervical dimension. Primary Mandibular 1st Molar
The mesial marginal ridge of the primary mandibular first molar is so well developed that it looks like a cusp and it could be considerd as "another small cusp" located lingually. Primary Mandibular 1st Molar
From a mesial view, the ouline form of the mesial root does not resemble any other primary tooth root since the facial and lingual surfaces are straight (do not converge apically) for more that half the root length. Primary Mandibular 1st Molar
A distolingual cusp is frequently absent and it is the most underdevloped lingual cusp present on any primary or secondary ____ . Primary Maxillary 1st Molar ; Primary or 2nd Molar
The facial bifurcationis closer to the cervical line (averge of 1.5 mm) than any other olar furcation. Primary Maxillary 1st Molar
Has the greatest root divergence of any primary molar with an average separation of 12.6 mm betwenn the lingual surface of the lingual root an d the facial surface of the mesiofacial root. Primary Maxillary 2nd Molar
The distal bifurcation is located farther apical to the cervical (average of 2.9 mm) than any other molar furcation. Primary Maxillary 2nd Molar
